Antipathogenic devices and methods thereof

Abstract

Disclosed herein are compositions, devices and methods for inactivating viruses, bacteria, and fungi. The compositions, methods, and devices may include coatings or slurries such as silicon nitride powder coatings or slurries for the inactivation of viruses, bacteria, and/or fungi.

What is claimed is: 
     
       1. A method of inactivating a plant pathogen on a plant comprising:
 contacting the plant with a composition comprising silicon nitride at a concentration of about 1 vol. % to about 30 vol. % with the pathogen. 
 
     
     
       2. The method of  claim 1 , wherein the composition comprises a slurry of silicon nitride particles and water. 
     
     
       3. The method of  claim 2  further comprising:
 spraying the composition onto a surface of the plant to contact the pathogen. 
 
     
     
       4. The method of  claim 1 , wherein the pathogen is reduced at a location in or on the plant. 
     
     
       5. The method of  claim 1 , wherein the composition comprises silicon nitride at a concentration of about 5 vol. % to about 30 vol. %. 
     
     
       6. The method of  claim 1 , wherein the silicon nitride inactivates the pathogen. 
     
     
       7. The method of  claim 1 , wherein the pathogen is a fungi. 
     
     
       8. The method of  claim 1 , wherein the pathogen is  Plasmopara viticola.    
     
     
       9. The method of  claim 7 , wherein the plant is Cabernet Sauvignon or Cannonau. 
     
     
       10. The method of  claim 1 , wherein the composition is in contact with the pathogen for at least 1 minute. 
     
     
       11. The method of  claim 10 , wherein the composition is in contact with the pathogen for at least 30 minutes. 
     
     
       12. The method of  claim 10 , wherein the composition is in contact with the pathogen for at least 1 hour.
